Here is the user model:

class User < ActiveRecord::Base
    before_save { self.email = email.downcase }
validates :name,  presence: true, length: { maximum: 50 }
 VALID_EMAIL_REGEX = /\A[\w+\-.]+@[a-z\d\-.]+\.[a-z]+\z/i
  validates :email, presence: true, format: { with: VALID_EMAIL_REGEX },

uniqueness: { case_sensitive: false }
  has_secure_password
 validates :password, presence: true, length: { minimum: 6 }
  validates :password_confirmation, presence: true

Answer 1

You have defined the following routes,

users_new  GET    /users/new(.:format)                 users#new
root       GET    /                                    static_pages#home
signup     GET    /signup(.:format)                    users#new
help       GET    /help(.:format)                      static_pages#help
about      GET    /about(.:format)                     static_pages#about

In static_pages_spec.rb, you are accessing routes as visit '/static_pages/home', visit '/static_pages/help' and visit '/static_pages/about' which would obviously result in No route matches error as these routes don't exist (match them against the routes listed above).

You need to make following changes in static_pages_spec.rb:

1. Error: No route matches [GET] "/static_pages/home"

   Replace

   visit '/static_pages/home'
   

   With

   either visit root_path or visit '/'

2. Error: No route matches [GET] "/static_pages/help"

   Replace

   visit '/static_pages/help'
   

   With

   either visit help_path or visit '/help'

3. Error: No route matches [GET] "/static_pages/about"

   Replace

   visit '/static_pages/about'
   

   With

   either visit about_path or visit '/about'

You receive next 2 errors in user_pages_spec.rb file:

1. Error: undefined method 'full_title'

   It clearly gives the clue that you are using a method named full_title which is not defined anywhere.

   it { should have_title(full_title('Sign up')) } 
                          ## ^
                          ## full_title method here is undefined
   

2. Error: expected #has_content?("Sign up") to return true, got false

   This error simply means that the following example is failing

   it { should have_content('Sign up') }
   

   That means sign_up view does not have the text Sign up. Make sure that sign_up view has the text Sign up exactly, match the exact case as well.
